FAQs

About the Cadillac CT5

About the Cadillac CT5

The CT5 is the larger of Cadillac’s two current sedans, sitting above the CT4 in the lineup. It was launched for the 2020 model year as a replacement for the Cadillac CTS, and has remained in production since then without a redesign.

What are the advantages of the Cadillac CT5?

Stylish design
Multiple powertrain options
Fun to drive

What is the best Cadillac CT5 model year?

Cadillac hasn’t really changed the CT5 since its 2020-model-year launch, but a refresh is coming for the 2025 model year.

What are the disadvantages of the Cadillac CT5?

Not much cargo space
Advanced safety features are not standard
Mediocre interior design

Comparison: Is the Cadillac CT5 better than the BMW M5?

The CT5 isn’t really comparable to the BMW M5, a performance version of the BMW 5 Series sedan. The standard 5 Series does compete against the CT5, while the CT5-V Blackwing version of the Cadillac is the true M5 rival.

Is the Cadillac CT5 a reliable car?

The CT5 received a good reliability score of 85 points (out of a possible 100) in the most recent J.D. Power customer satisfaction survey.

Is the Cadillac CT5 worth the cost?

Competitive pricing means the CT5 is a pretty good value compared to other midsize luxury sedans. A good balance between ride quality and handling also makes this Cadillac feel like a real upgrade over sedans from non-luxury brands.

4.7 Overall rating

(56 reviews)

Customers say

The Cadillac CT5 is well-regarded for its impressive performance, handling, and comfort across various model years, especially the sporty CT5-V version. Owners appreciate its powerful engine options and smooth ride, often highlighting the stylish design and advanced technology features. However, some drivers have noted visibility issues, discomfort in the driver's seat, and concerns about its competitiveness against rivals like BMW and Mercedes. Overall, the CT5 is seen as a great value within its segment, blending luxury with practicality.

This CT5-V was loaded with all the options. We were pleasantly impressed with the quality, comfort and handling. The only other car I would’ve liked was the CT5-V Blackwing.
